Bridge swivel structure

Abstract

The invention discloses a bridge rotating body structure. The bridge rotating body structure comprises a stainless steel sliding plate, wherein connecting plates are arranged, at positions close to two side surfaces, on the upper surface of the stainless steel sliding plate, the bottoms of the connecting plates and the stainless steel sliding plate are movably connected, a stop block is installed between the two connecting plates, the two ends of the stop block extend into the connecting plates, the lower surface of the stainless steel sliding plate is connected with a protection plate, the protection plate and the stainless steel sliding plate are connected through a built-in sliding groove, supporting columns are installed, at positions close to two side surfaces, on the lower surface of the protection plate, the tops of the supporting columns are fixedly arranged on the protection plate, the bottoms of the supporting columns are fixedly arranged on a wear-resistant plate, and a steel structure plate is built in the wear-resistant plate. The bridge rotating body structure has the advantages that the clearance fit tightness is good, the friction coefficient can be effectively reduced, the horizontal rotation stability is guaranteed, the purpose that the vertical rotation can be positioned during presetting an angle is achieved, the bridge is prevented from exceeding the preset angle and better wear resistance and shock absorbing effects can be achieved.

Description

technical field [0001] The invention relates to a swivel structure, in particular to a bridge swivel structure. Background technique [0002] With the rapid development of my country's highway transportation industry, swivel bridges are more and more widely used in bridge construction. Compared with previous construction techniques such as cantilever assembly, cantilever pouring, and in-situ cast-in-place, swivel construction has the advantages of not interfering with traffic, not Intermittent navigation, can cross deep ditches, rivers and roads with frequent traffic, fast construction, high economic benefits, etc. The swivel support system is the core component of the swivel bridge and plays an indispensable role in the swivel of the bridge. Due to the large bearing moment of the general bridge swivel, the horizontal rotation is realized through the friction between the rubber pad and the steel parts, but the friction coefficient between them is large, which makes it difficul...

Due to the large bearing moment of the general bridge swivel, the horizontal rotation is realized through the friction between the rubber pad and the steel parts, but the friction coefficient between them is large, which makes it difficult to realize the horizontal rotation, and the general swivel structure There are certain deficiencies in its own connection performance, and it cannot play a better role in swivel
